Trying to stop bolt catch breakage and still able to shoot 115 gr 9mm ammo. I'm currently waiting arrival of a 308 buffer spring and neoprene buffer spacer. I ordered these from JoeBobs outfitters. I will be testing them after they arrive. I wonder if this is over kill? I have also discovered a stainless steel bolt catch for sale on line and wondering if anyone has tried one of these?

I just purchased a 308 recoil spring and a carbine buffer spacer from Joebobsoutfitters.com for my 9mm build with 16" bbl. They arrive Wednesday. Now after studying and watching youtube comments on this combination comes the concern will this interfere with the choice of ammo? I plan to mostly use 124 gr and 147 gr ammo but 115 grain ammo would be nice to use at times. Any thoughts on the subject?
