RangerMcFadden Posted September 27, 2023 Share Posted September 27, 2023 …yeah, ‘cause that would be the worst thing that could break right before your major match. Thankfully, a friend let me take one of his apex hammers outta his gun after calling every gun store in a 5 hour radius and Apex said they had no way to overnight anything. I don’t wanna restart the ol’ debate of the effects of dry firing a Revo but I would like to point out the firing pin lasted longer than the hammer.

21 shooter Posted September 27, 2023 Share Posted September 27, 2023 What model is that and is it MIM? I do very little dry firing on any S&W unless it’s a frame mounted firing pin. Perhaps I should reconsider. It’s also nice to have good friends! Link to comment Share on other sites More sharing options...
Bill Sahlberg Posted September 27, 2023 Share Posted September 27, 2023 I have dry-fired both frame & hammer firing pins since 1974 and never have had a problem... Link to comment Share on other sites More sharing options...

It’s probably got over 100,000 dry trigger pulls on all these parts. I wouldn’t worry about it. 10 minutes ago, Bill Sahlberg said: I have dry-fired both frame & hammer firing pins since 1974 and never have had a problem... You shouldn’t it’s an old wives’ tale that you shouldn’t dry fire a revo. I just needed a clickbait title to draw you in to see my bad (possibly good?) luck.

ltdmstr Posted September 27, 2023 Share Posted September 27, 2023 Seems like not such a great design to have that big cutout right where you have all the force of impact. Like exactly where it broke. Link to comment Share on other sites More sharing options...
MWP Posted September 27, 2023 Share Posted September 27, 2023 I have over 750,000 live rounds on one of those hammers and several million dry fires and haven’t seen it break. This is truly a unique case. Link to comment Share on other sites More sharing options...

Agreed; I’d say I should get a lottery ticket then but the real lottery tickets are 1.) it not breaking stage one at the IRC and 2.) having a buddy with a spare.

gargoil66 Posted September 27, 2023 Share Posted September 27, 2023 I would like to see the wear on the hammer but my bet is that this particular hammer had problems when made that no one could have found. Not really surprised but have never seen it happen before. I doubt S@W, Ruger, et al., ever intended their firearms to take the prolonged use and abuse that a competitive shooter will produce. The aftermarket competition parts are also probably more sensitive to installation and alignment with other parts. Not particularly worried about any of it. Will continue to dry fire but I do use snap caps. I believe snap caps do protect the firing pin from damage. GG Link to comment Share on other sites More sharing options...
Petrov Posted September 27, 2023 Share Posted September 27, 2023 I have about 35,000 live rounds and about 300,000 dry fires through my Apex hammer. The only issue I had was the sear pin walking out and binding the action up. Sometimes s#!t happens. People who install things like Apex hammers into their revolvers tend to be people who shoot their guns a LOT. First time I seen this happen to an Apex hammer and I had mine since they came out.

superdude Posted September 27, 2023 Share Posted September 27, 2023 I broke a firing pin on a S&W 686 with a hammer mounted firing pin while dry firing. It does happen. Link to comment Share on other sites More sharing options...
Toolguy Posted September 27, 2023 Share Posted September 27, 2023 (edited) All this anguish can be easily and cheaply prevented. All you have to do is get a 5/16" OD x 3/16" ID (metric equivalent would be M6 ID x M8 OD) rubber O ring (or package of them) and put it in the frame over the back of the firing pin for frame mounted, or over the firing pin hole for hammer nose models. It will go from round to oval when you install it. The side tension keeps it in place. This is a good safety measure as well. The gun won't fire with the O ring in place, if the gun somehow gets ammo in it. Then you don't need expensive snap caps and have way more protection for the firing pin, spring, hammer, frame, etc. All of these are cushioned and protected by the O ring. This also makes dry firing quieter in case someone in the next room doesn't want to hear all the clicks. Your scores will benefit greatly by removing the O ring before the match.

Couch-Commando Posted September 27, 2023 Share Posted September 27, 2023 I use Tippon snap caps religiously for everything. I was also told it was safe to dry fire a Glock, but that didn't prevent me from cracking the breech face of my Glock 17! Link to comment Share on other sites More sharing options...
Alaskan454 Posted September 27, 2023 Share Posted September 27, 2023 Curious, do you use spent cases or snap caps when you dry fire? These sort of failures are exceedingly rare. Link to comment Share on other sites More sharing options...
Petrov Posted September 27, 2023 Share Posted September 27, 2023 Quick question. My hammer has this sight protrusion below the striking surface and this protrusion is hitting the the frame, is that by design? I have some deformed metal below the firing pin area where it keep hitting. Its not hitting the sides of the frame but below the firing pin.

Toolguy Posted September 28, 2023 Share Posted September 28, 2023 On the N frame, that part hits the frame and keeps the upper part just barely off the frame so it doesn't peen the firing pin hole. The K and L frame has an angled surface there that does the same thing. Link to comment Share on other sites More sharing options...
