Running 10mm mags in Stock 2/Stock 3 .40cal?

[nitrohuck]

Am I correct in reading that the .40cal Stock 2 or Stock 3 will accept 10mm mags? Thus allowing you to run longer OAL's in your ammo?

 

I am going to pick one up to use as both a limited backup gun, as well as a production gun, but would prefer to leave my current OAL as is on the press. If something happens to my limited gun, I need my backup to be able to run the same long OAL ammo that I'll have on hand at the match.

 

If running 10mm mags in the .40 Stock 2 or Stock 3 will solve this issue for me, it will be a huge convenience to say the least.

Correct, however you must test your barrel with the plunk/spin test to make sure that your rounds will chamber. Reaming to increase the headspace might be needed.

No problems running those magazines, like he says though, check what OAL your barrel will take.

Any reputable places to send my barrel off to?

Patriot defense, great company to deal with

Thanks for all the responses. I don't run excessively long ammo for limited (about 1.180") so hopefully I don't need to do any barrel reaming. From what I've read people have been able to chamber ammo of that length no problem. I'd rather shorten my ammo a few thousandths than ream the barrel anyhow

The best thing about the 10mm magazines is that you can also run factory length ammo without any problems, at least I never had any issues
