i've lost count of how many PSA 35 rounders i've got and i don't give a crap about the drop free stuff....i've never had a misfeed on any of them...recently i added a couple of the 15 round extensions and they run flawlessly also....
Also if youve got one of those extended mag catches you'll be glad they don't free when you bump it when trying to get the scorpion in action when you're trying to retreive it from the passenger seat and the mag falls out in the floor....
i did get a couple of the clear ones recently and had to sand the bump on the front edge of the mag so they would go in and out without a lot of force....D I C K
