I bought a 357 Sig EFK barrel for my Glock 35. It's really not what I thought it would be. The overall length of a loaded 357 sig cartridge is around 1.125". Anything longer and the rounds hang up in the magazine. The overall length of just the empty cartridge is around .855". So you have basically .270" of bullet that can hang out of the casing. When I seat most 9mm bullets (Lead/FMJ) to the COAL of 1.125 the bullet can be pushed back into the case with your thumb. Naturally, if this happens while the cartridge is being fed into the barrel, it will raise pressure levels to the point of perhaps exploding the barrel. It appears that the only bullets that will work with this damn caliber are going to be expensive hollowpoints. Are any of you guys out there using a lead or plated bullet that works well with the 357 sig? I should never have gotten rid of my custom 1911 in 9x23 caliber. That sucker was accurate and you could feed any bullet from 88 grain to 160 grain with no friggin problems. Lesson to be learned, buy guns, never sell them.
