At first I had the slide on my DW Panther frame, which IIRC has a 17 pound mainspring. The hammer strike was not heavy enough and I was getting *many* misfires and squibs. I believe part of the problem was that the firing pin was binding and not moving freely. It has loosened up considerably now.

Then I put it on my Colt frame, which at the time had a 23 pound mainspring, and I didn't have any more misfires, but massive feeding problems.

If I had it to do over again, I'd definitely get the GSG instead of trying to fool with the Mimber slide.

Here is a list of the things I have done to try to get the darned thing working:

1 - Polished and greased the firing pin to try to eliminate misfires

2 - Changed frames

3 - Changed mainspring (23 to 19 pound)

4 - Modified two of three magazines to remove excess material at the top

5 - Tried different ammo -
--Remington Thunderbolts, (burns so dirty they won't chamber after 50 rounds, half are subsonic and half supersonic, many duds)
--Remington Golden Bullets (many duds)
--Federal Champion Plated Hollow Points (1 jam out of every 20 rounds)
--CCI Blazers (1 jam out of 100 rounds, burns a bit too dirty)
--CCI Mini-Mags (seem to be the only thing that works but are too expensive)

6 - Tried running a boresnake through every 50 rounds

7 - Polished the rails

8 - Switched from Wilson grease to RemOil on the slide to reduce drag

9 - Modified the firing pin retainer
