1st round in magazine sometimes jams
I carry my Sig P229 .40 in a 12+1 configuration in a 12 round Metsgar (spelling?) magazine carrying Ranger T 180 HP's.
Sometimes when going to the range I find out if I decide to shoot my Ranger T ammo, picking it up straight from the holster and firing it, the second round (the first in the mag) will jam and not feed into the chamber. Beforehand if I take the mag out and slap the mag against something hard with my hand it seems to "seat" all the rounds in the mag. right so I don't have that problem.
Any ideas what's causing the problem to feed into the chamber? The other rounds in the mag. shoot fine. It's just the 1st round in the mag. that's causing the trouble. Both mags have around 1,000 rounds thru them and the gun has around 2,000 rounds total.
