What’s your vector, victor? It’s a rotating mass, the math is beyond me. I’m not getting how you distinguish energy from momentum, which is….energy.

Great post Bob. I’m actually looking at this exact question from a lock-time perspective, really curious about the legendary SA hammer/ trigger combo. Totally agree about the energy numbers.

Nice find. That’s one on my wish list.

I made my own after bending several on a particularly difficult job. If someone would like to try them out for the cost of materials and shipping, DM me. Not sure what the mods think about this. I made a starter punch and a long punch for finishing the job.

I’m guilty, but only with the springs out. Great points: Don’t do it Don’t mention it

I’d be very careful about polishing the forcing cone on your own. The angle is important, as is the centering of the cone on the bore. You might make a bad problem worse. If this got noticeably worse during a match, I’d look for something that went south and affected timing. Ratchet damage...

Just saying, the single stack guys had the same complaints. It's all about stage design that forces reloads in place.

I made these to deal with a serious bubba problem that had bent several commercial & DIY punches. The starter punch is a game changer.

Great write-up on matching barrels. The more I goof around with this the less mystifying it is. I would add one thing for the folks in the back row - take a really good look at the mating surfaces on the frame and the barrel. I had a take-off that was gritty and galling bad. It would thread...

I'm in the same boat but find an N frame donor ain't easy. It would make a very unusual Pinto. Performance Center version!

As an aspiring shade tree gunsmith I’d say you made the right call. That pin is under a lot of pressure, the pin must be pressed in to a very precisely drilled hole.

DA & SA?

Something different, you say? I have some ideas.

You are the man. It’s in jail, I’ll let you know when it is in hand.

It’s a 5-digit serial number .32-20. What are the odds a more modern version will fit?
