So I have this Remington R1 long slide 10mm. The gun shoots accurate enough with the right loads- an inch at 25 yds. BUT, it throws brass almost 25 yds behind me. I've tried several different recoil spring weights and none have effected the issue at all. I even got the Wolfe Super Power spring that you have to size to the weapon. Nothing changed. It was suggested to change the hammer spring and use a flat bottom firing pin stop. That flat bottom pin stop changes the geometry and speed of the slide in opening. The gun came with a flat bottom stop so that wasn't anything I had to work on. I bought a suggested 25lb hammer spring and put it in yesterday evening. While I haven't shot the gun yet, the difference is day and night. Frankly, I doubt there are many women that could rack the slide now. It's hard for me and I'm no weakling. I have no clue what the original hammer spring was but I have a feeling that the factory original recoil spring might be going back in the gun. I can't get to a range until Thursday next week so I'll be looking forward to shooting it next week. Thanks for the suggestions. I'm thinking I finally have a grasp at the mechanics of the 1911.
Just when I think I understand a 1911, I find out how wrong I am. :P
Chances are the factory spring was a 23 lb. 2 lbs makes a huge difference when combined with that flat bottom stop. Like you, I can rack the slide, but it is a bit of a chore. I just cock the hammer by thumb first.
Let us know how it goes at the range.
Well, I just got back from the range. I had high hopes that the Wolff super recoil spring and the 25 lbs hammer spring with the flat bottom firing pin stop would tame this beast. I was wrong. It throws brass just as far even with 135 gr plinker loads. So I guess I'm clueless how to keep this thing from throwing brass into the next county. It does make me wonder though, how much was the gun taking a beating before the heavier springs. FWIW, the heavier hammer spring didn't seem effect the trigger pull any but it did seem like the recoil was less. It just might be some of the felt recoil was the slide slamming into the back of the frame or maybe the guide rod. Don't know cause what I thought I knew about a 1911 is now out the window. I'm just as much a moron as when I started. BUT, I did shoot several 1" groups at 25 yds with the load I settled on. 180gr HST with 12.8grs 2400 at 1.255.
Another "duh" moment at the range. I also took my Colt Special Combat in 38 Super to play with some loads. That's when I noticed something that made me go "HHMMMM?" The 38 Super is a 10mm on a diet or you could also say the 10mm is a fat 38 Super. Same dimensions for OAL and trim length. Never noticed that before. No wonder I like the 10mm so much. It has a lot in common with an extremely accurate cartridge.
