Too expensive - Apex Tactical Specialties Action Enhancement Trigger and Duty/Carry Kit for S&W M&P Shield

It's a pain to put this kit in compared to other after market kits for different gun manufacturers. You definitely need a vise for this kit install. The changes/improvements were noticeable but not for a $160. The improvements didn't "knock my socks off" like the $30 spring kit I just put in my Glock. With all the parts that came in the kit I thought I was going to amazed at the improvements. More like, "Meh..." Guess I shouldn't compare it to other gun manufacturers aftermarket kits. I would've saved my $160 and left my gun stock.
