M&P or Glock

I do not use extra power springs, my guns are not set up for that. and what extra power recoil springs do is slam the side forward harder causing the front sight to nose dive.

 

I am referring to extra power magazine springs. When the M&P auto-forwards it is usually because you slammed the mag in pretty solidly, And with the stock mag spring the rounds will sometimes drop down (inertia) and cause it not to strip the first one. By using a heavier mag spring it keeps it from dropping and allows the first round to chamber normally.

 

This has nothing to do with recoil springs.

sorry that is what I though was being talk about.

any way all our standard mags (idpa) and I think some of my on limited mags had factory springs. I know they where on that way at first on my limited.

 

when I was trying to get my M&P's tuned a strong mag spring will not let the gun function with at light recoil spring. that's how I would get out of battery shots with a 11# spring and once with a 13#. 

as recall I am using a sprinco 14# recoil spring in my Limited and IDPA gun with a 128-130 PF.

 

the auto forward before I got hurt  I had no problem.

Put the LEM trigger in your USP; that will be the ticket. 

 

I got the LEM in my USP it is pretty sweet. Just the reset is longer than the glock and it's funny to watch me when I don't let it out enough LOL.

I haven't had any issues with my 34 using extra power springs in my TTI base pads.
