Anybody ever have any issues with the firing pin going too deep into the frame and popping out on the primer side too far. I believe my 15-2HV's firing pin protrudes too far. If it's at all possible, would somebody please measure how far the firing pin extends from the frame to the primer.
I'm trying to save this 1977 model. It's seen its days of abuse by a former owner. I've replaced the firing pin and spring, cleaned the pin bore but it continues to stick making the cylinder opening a problem.
Thanks greatly,

You may have one of the older firing pins in a newer model 15. There was a change in the firing pins somewhere along the line--I'd have to dig up the reference to find out when.

Thanks.
Given the '77 proof of purchase I recieved with the gun, I thought this was an older model.
For whatever it's worth, this model's frame side cover has the pop in and out cylinder stop. I guess there was a change on sidecovers along the line also about this time/production date. Also, this gun looked good but when taken down and run thru a check out showed a lot of abuse. Rusty internals, warped frame, warped barrel to frame, stripped threads on the sights, beat wood grips. At least it came with the original set of tools!
Do you know the approximate date the pin change was made? Or the proper firing pin protrusion depth from the frame to the primer?
Take care, and again, thanks greatly

OK, here ya go. this change was pre 15-2, so it shouldn't apply to your situation, but you never know. I suppose it is possible you got an older firing pin. "
The original firing pin had a straight shank measuring .075” in diameter. The new firing pin is tapered, measuring .100” at the base and tapering to .075 at the tip—a larger tapered spring was also implemented."

Forgot to ask--what makes you think the protusion is too far? Are you piercing primers? Let's see some pics of this beauty

Thanks greatly for the pin measurements. This one is tapered. I started getting miss-fires, then holed a primer. I thought the load was too hot, double checked -nope. 170 FMJ Sierra, 16 gr. Lil' Gun on one load and the load that popped a primer, 158 Hornady, 15 gr. of H110. Fed case, CCI mag primers. Sooooooo, I did a visual against my other revolvers (Pythons and Diamondbacks-sorry) and it appear the DWA pin protrudes too far towards the pin/ away from the frame.

Without tearing into one of my DW's, I'm not sure what "stops" the firing pin from going forward. If you are piercing primers (and your loads are not too hot), there is definately a projection problem. Maybe another DWF member has some inside info on firing pin problems.

I don't know for certain, but I don't think there was ever a point that the cylinder stop was a separate part. On my '78 15-2, at some point in time I broke the cylinder stop thru (I think) careless reassembly. I was told by the folks at CZ/DW that the cylinder stop part they have in inventory is a part manufactured to solve this fairly common problem. I have never seen a parts diagram that shows it as a separate part.
Further discussion here:

I went to a bookstore and asked the saleswoman "Were is the Self Help Section?" She said if she told me, it would defeat the purpose.

They never put a p/n on the cylinder stop. My 15-2 is a '77. It does have a replaceable cylinder stop.
Anyhow, my problem with the firing pis is that it sticks down in the firing position. But looks like it's going too far into the primer. Based on my Colt's (of which ammo does not care who the OEM is), the pin of the DWA seems to be going to deep into the primer. I've removed and replaced the correct pin as verified by DWA and cleaned the pin portion recess into the frame to no avail. Additionally, I've even tried a Wolff main spring, original main spring, and a new DWA main spring. Still sticks. My loads are not hot and I don't shoot heavy bullets. 158's across the board, jacketed or lead. The gun is a real delight to shoot due to the light loads (and the patridge front and Millet rear).
If I knew how far the pin pops out toward the prime, I can measure mine, and go from there. Althought, I'm still not sure why the pin stays depressed into the frame on occasion.
Thanks all, for your comments.

I'll measure a few of mine tonight, but it sounds like the frame hole may be opened up to far (if that is possible).

That's kind of what it sounds like to me too...in my unprofessional opinion.
Sounds like maybe the gun has been dry fired a lot & it's worn the area in the frame surrounding the firing pin.
Just a guess.

Yes, exactly where I was going by requesting pin protrusion to primer measurement. If I had that measurement, I have a base to determein where my 15-2 stands.
I'm confident I can repair this baby even tho it's been run thru the ringer. When I called DWA, nobody could assist me. "Why do you want to know this?" -or- "send it in" was the response. Sorry, but I don't want to wait 9 months. Last time I sent a gun in, they lost it. Not going there.
Sorry to sound pissy. I'm actually not in real life. Love my revolvers, every one of them. This one's (15-2 HV 8 inch) a hotrod of sorts, can be saved and shot in IHMSA and win. Althought I dearly love my Colt's, my respect for DWA revolvers is there in spades. Matter of fact, I held the Colorado state revolver record for years with a .44 mag DW. Miss that gun, A LOT!
Thanks greatly all!!

Sent to DW/CZ, or some other place? Regardless, that's not cool...did they replace it?
I'd offer to measure mine, but I don't have a micrometer that will get in there & get me an accurate measurement. Maybe I'll go hit Sears in a day or two & see if they have one that I can use last Christmas's gift card on.

Not sure if this is what you wanted but I made a quick try last night. With the hammer down the firing pin protrudes approximately .025. If I push the pin all the way forward past contact with the transfer bar It protrudes approximately .035. The firing pin spring was supprisingly strong. Does the pin stick if you push it forward manually?

Hey Charger, save your X-mas card for your kids. Yup, they replaced the gun, an 8 inch .22. Took a year. Water under the bridge.
My pin, pressed as deep as I can go with it, pops out .045 inch. My Python is .038, my Anaconda is .035 and my wife's 686 is .040. Based on Ibruce, my pin travels too deep and gets stuck. Sooooooooo, I can take a bit off the primer side of the pin, and start reworking the pin hole in the frame.
Thank you both. I'll let you know how this venture goes. Some day when I get time, I'll type up how I managed to get my DWA .44 Mag down to 1 1/2 inch groups with iron signts @ 100 meters and 1 hole 5-shots at 50 yards. I've applied this to other Dan's I've gunsmithed over the years with similar results. I WISH Wesson offered a .357 barrel with a 1/14 or 1/16 twist..........maybe I can special order one and put it on Chargers card. LoL! Thanks!

I measured my 715 and it protrudes .050 with the trigger held back in the firing position--hammer at rest. (Monson gun) -- So I checked two other 15's, also right around .050

I was thinking we could each fire an empty primed case to check some measurements, but we would all have to seat primers the same depth and have similiar hammer strikes. I do know all my DW's have really nice dents in the primers, almost like a mauser action. I'm going to fire an empty case today just to see how it looks--granted it won't be exactly the same as a loaded round, but it should be close enough...the mystery continues

I rechecked my M 715 alittle closer this morning and it is closer to .030 in the fired position. I also checked my M 15 and it protrudes around .035 in the fired position. I have a few questions if you don't mind.
Does the pin stick if you dry fire it?
Are you using the tapered pin?
Does it stick with both the straight and tapered pins?
I am no smith but have a hard time thinking the length is the problem. If it sticks when dry fired I believe it has to be in the firing pin to firing pin well relation. Any way just my opinion. I hope this helps.

OK, .015 is a big difference between our measurements (yea, we're probably both dead on)... how are you getting your measurements? I unscrewed the barrel and set up a depth mic on the frame face and set zero at the firing pin hole. I then "fire" and hold the trigger back; my depth gauge then goes to .050 -- not exactly laser perfect, but as close as I can get.

Hey Shoot, Your method is probably a little more accurate as I just used dial calipers, But I did it from two different directions and came up pretty close both ways. I may be nuts but I don't believe .015 will make a big difference. The pin will only go as far as the hammer drives it and shouldn't stick unless it pierces the primer and I understood that only happened some of the time. Of course all of this is just guessing on my part. Sooner or later CJ will whip the problem solving the mystery and hopefully enlighten us as to the answers.
