Just got back from the range i put 100 rounds through my glock 19 and 100 rounds through my glock 27, absolutely perfect. The only problem was my fault i was shooting my 27 using a 15 round mag, and accidently grabed my 19 mag loaded it and chambered it it fired a dud i dint know wtf happened i pulled out the mag and realized what i did. Put the right mag and it was perfect, does anyone think that coukd have caused any damage. I also shot my little taurus tcp about 75 rounds perfect as well got i love that little 380. Anyway it another great day at the range and figured i would share.
