642 PC vx 637 PC

[Practical]

The 642/442 guns lack an internal component which is part of the safety system for single action guns to prevent accidental discharge.

This component serves NO purpose on double action only guns and in my opinion the lack of it improves the trigger and also improves reliability.

The ONLY part to ever break for me in 20 years use of J-frames is that part. S&W fixed it free of charge and did slick up my trigger and ratchet star for free, but my revolver was down. It failed on the 2nd click of dry firing with snap caps.

I am leaning toward a 442 next time if they make a 442 PC or maybe a 442 Pro!

Though I too will look at a 642 PC and a 637 PC.

I've always had a strong preference for SA, and currently own three 637-2s.
All three with titanium cylinders and two also converted to 9mm.
SA trigger is about 1.5 pounds. DA pull is pretty heavy, but smooth.
I invariably shoot SA.

Great choice sir. Something else to think about is if you ever buy a J frame, standard or PC version, I have always dry fired mine at ;east 3000 times before carrying it and then take it to the range for a session of practice with my carry ammo. I know this sounds like allot of dry firing but you can do it in a few days pulling the trigger 100 times at a time. I can tell you that my standard triggers on my 442/M&P340 & 640 Pro have sweetened up very nice. Anytime you can get trigger time on your j frames, do it. Dry fire practice serves both in that you get trigger control practice and it will begin to smooth out the internal parts of your j frame. I know it has worked on the 3 I currently have and my last 640 as well.

I think you chose well. Every PC revolver I've ever fondled did have a better trigger than stock. And I think the heaviest triggers I've ever felt on a smith was a 637. My 442's is about the second heaviest I've ever felt. I would have not have chosen it, but I bought it from my Mom when my Step Dad passed cuz she needed the money. I still shoot it rather well for how heavy the trigger is. It has gotten a little lighter and a little smoother with shooting, dry firing and I let some clp run down in there from the trigger to help lube the action.

But this is neither here nor there since you got a really nice trigger! We need pics though. Or it didn't actually happen. hehehehe

Thanks Eagle1*, I never thought about this for a revolver. I've racked my semi-autos a few hundred times before taking them to the range, this gets the slide smoothed down and greatly reduces the chance of a eject/feed problem. I started this with the first new Ruger LCP I purchased. I cleaned it before going to the range and had several feed problems. I called Ruger and the tech I got suggested that I rack it 200 - 300 times, clean it and try again. Never had another problem. I'll give the 642 some exercise.
