Grand Power K40 10mm Owner Review Video

That is unfortunate, please keep us informed.

Is the first and last rounds sitting level in the magazines? Maybe the front of the lips need a tweak?

Man it feeds great as long as there are more than one rounds in the mag. If I load just one round in the mag then try to chamber it will not even chamber all the way . I know the mag is releasing the round because I can eject the mag after it locks up and the lips are not touching the round. Only thing I can think is it might be the angle of the  follower . hope they can fix it . I will keep you guys posted.

In this case I don't think it's the pistol and suspect something with the magazines.

Yeah I think it's the mags. Just got my boss to call our sales rep at Davidson's (i work in a gun shop). The are sending me a new gun and should be here in few days. Also sending call tag for the old gun. We will see if this one is any better. Crossing my fingers lol.

I made up a half dozen dummy rounds to cycle thru the mags and action of my GP, all different type of bullets just to be sure is isn't a bullet type issue. After spending 2-3 hours emptying mags thru the gun I can only reproduce the last round ftf consistently when I slowly release the slide. When I release it from fully open it only jambs randomly. While watching the bullets feed operating the slide somewhat slow it appears that the mag follower is not throwing the case head up as fast on the last round making it jamb. IF...I am right does anybody have any ideas on how to correct this without compromising the first 13 rounds?

What color is your recoil spring?


Edit: Oops, you have the red spring don't you

It came with the longer silver one and I replaced it with the red one.

Still disappointed with my gun after warranty work. Magazines still drop fro. The mag well with full power loads. Still jams frequently. It's a bitch to reassemble to. Overall can't recommend it to anyone. I love my Smith and Glocks way more.

Does the K40 follower look similar to my K100 9mm?



That center knub could be a limit problem for fitting 14 rounds.
