I am very new to firearms, and the forum. Took the 101 class out at Clackamas PSTC with a S&W 638 snubby. I intend to carry this piece once I have my CHL. I also plan to follow up the 101 class with other offerings from PSTC and maybe take a trip to OFA or SFA and get proficient with a pistol. I have been renting different models at the ranges and have decided on the Walther P99, or perhaps the S&W 99, one of which is available now for a decent price at a local shop. Here's my question: the Walther I have shot with twice now, and really like, has a mag that is very, very hard to fill. That tenth cartridge is almost impossible to squeeze in there, and being rather new (and very cautious) I'm afraid of breaking something, or worse. Is this common to the Walther mags, or is the one I'm renting perhaps needing some reconditioning? Thanks for your help, this is a great forum!
