So you own a J-Frame.....now what

Can I ask the weights of the rebound and main spring? I'm trying to get an idea of how this would compare to the Wolff kit with the 13# rebound and 8# main spring.


I want the answer to this question also.
 
5.5 on the rebound and 6.5 on the MS. At a compressed length I specified in the engineering process.
 
The J's are strictly for self defense and I leave them as-is. Constant practice will enhance your abilities and smooth out the trigger.

+1

The hard trigger pull is the safety on this gun. In a self defense situation this gun is designed for, you'll have more than enough adrenaline to pull the trigger.
 
How soon after the NRA show will these be available at Midway, Brownells, etc?
 
Yes and 5.5 on the rebound is even lighter! I have no personal experience with this but I've read where people say they can out shoot the trigger return of a 13# rebound.

Is a 5.5# rebound spring a recipe for disaster, or does it just somehow work in this kit?
 
If I ever get the burning desire to buy a 3" M60 and use it as a range gun, I might look into this kit.
 
Will this work with the .22 rimfire J Frames? I'm eyeballing an 8 shot snub (like a 43C) and these rimfires tend to have the stiffest trigger pulls, often out of necessity. Will your kit work with these?

And what about the Centennials, both old and new? My 940 is the only revolver I own that I have never disassembled, because it was so good when I bought it. I didn't need to change a thing. I ordered a spare firing pin from Brownell's to have one just in case, and they sent me what looks like a common frame mounted firing pin. I believe that this is the wrong part. So is the Centennial firing pin different and can you accommodate?

And regardless of new or old, frame mounted or hammer mounted, aren't the coil mainsprings and rebound springs all the same as they come from S&W?

As soon as Brownell's Approves them through their new product process and Midway does the same they should have them available.


They'll go up on the Apex site within a few days of us getting back.
 
On the spring weight questions.....He's the thing.

When you measure spring force, you have to take a force reading at a certain length. So if I have a spring that is for example 2" long at free length and I want a force reading, where do I measure it? If I compress the spring all the way down until it coil binds I'll get a heavier reading than if I hold the spring at the max compressed length in the mechanism. After some careful calculations, I determined the length I needed the spring weight to be measured at and had my spring manufacturer run the numbers. At the compression I specified, the springs weighed in right were I needed them to.

I don't know how the other guys measure their springs, but I get the feeling they compress them all the way down for a reading. That would seem logical if I needed to give somebody a rating that could universally be measured easily.

The spring recipe we're using here is 20% heavier than those we've used in the past in customized J-Frames. We engineered that much extra into the springs because we need them to work in every gun every time. So far they've been working great.

As for the .22 guns, it's a different spring set entirely. The amount of force needed to make a .22LR go off is so much greater than that of a 38, so for the moment, no they don't work in the 22 models. I'm working on a kit for that and will let you guys know what we come up with.

I guess that's what I'm looking for, some type of rating that would help me decide which spring kit to buy. Wolff's for $10.00 or yours for...$15, $20, $30, $40...
So I would not have to buy both and install them to compare them.
 
I really couldn't be fair saying that ours is 100% the best bet, obviously I'm biased toward my own products.

Your best bet may be to wait and see what people say about the kit once it's released and make your determination from there.

Scott - I always appreciate companies that devote R&D toward guns I love! I will definitely pick up a set and give it a try.
 
Just got back from the NRA show, picked up three kits (2 for me, 1 for my brother) on Friday. Went back to hotel room that night and put one in my 642-1 (brought my tools as I planned on doing this if I got a kit). Was greatly impressed with the difference. Went back Saturday and bought three more kits for friends. This is an awesome kit that gives a very nice trigger pull with strong trigger reset too. Everyone at the booth was very nice and informative. I want to thank all of them for being so helpful, especially with the firing pin as I hadn't done that before. Also thank you for the info on the M&P parts you make as I'm definitely wanting to get one now and deck it out with your parts. Range report to follow, I'm on vacation and will have plenty of time to wring it out.
 
Sonny,

LOL at "... brought my tools as I planned on doing this if I got a kit." We are cosmic brothers, anxious to get the goodies installed.

Looking forward to your range report and I'll be checking the Apex site so I can order one tout de suite.

Immediate gratification or wait for Grant Cunningham...........hmmmmm...... I'm pretty sure it's going to be immediate......

"pc load letter, what the F*** is that?" :)
