My son and I just came back form the range, after putting 200 rounds through my P220 and 300 rounds through my new MK25 and 250 rounds through my sons new P226 I am thinking about replacing my other guns to Sig's. On the MK25 everything we put in the mags it handled. Not one problem we ran out of ammo, now it's off the the store to get more ammo. I was telling my son that this is the best time that we have spent together. He is 33 and I am 59 and this is the best father son time we have had in a long time, he said it is the best time he has had to. Trying to show up the old man. (it didnt work he has a lot to learn). Any way My new MK25 is great I love it. I want another one.
