question. did you try to rack the slide to load that first round???If you did, then go back and try it using the slide lock release lever and see if it feeds OK. I would be suprised if it was the federal round .bigweb2001 said:
Unless you can't find any fmj ammo to break it in with then defense ammo is OK to break it in with but why use such expensive ammo for break in until it is right.
I can tell you on my P380 that recoil spring is one tough umbrey and is very diffiicult for me to rack the slide properly,but using the slide lock release lever, it works perfect. I know I will get better with it but there just isn't alot of slide to grab ahold of to rack properly and with what I think is heavy recoil springs, only adds to the difficulty. I have about 500 rouonds through mine and it works perfect when I do my part right alsol.
