Hi, I already got my unit from Squires last Jan.10 but, the 2 mec-gar mags are not included yet at still at the airport di pa raw nari-release. I fired 50rds of FMJ ammo the next day, nanghiram muna ako 2 mags sa Armscor MCS. On the first mag after finished 15 rds, hindi nag-lock ang slide, fired again on the other mags & finished the whole load without any problem. Fired again another 50rds of FMJ the next day still no problem, but I noticed the trigger pull is a bit hard. So, I brought my unit to a gunsmith to adjust trigger to 2.5lbs. Fired again the next day of 50rds of FMJ & still No problem, the trigger is nice. Fired again another 50rds of FMJ the next day, still NO PROBLEM! Finished 200rds of FMJ ammo, nice groupings & NO FTF problem! Now, I miss my gun!!! namron P.S: want to post pics but don't know how to post it!!!
