My son bought a Glock 23 but his hand is small and he couldn't hit the mag release without re-positioning his hand so he bought a couple of aftermarket upgrade parts to make it easier for him to disassemble and drop the mag. He came over and I thought he wanted me to do the transfer of items for the 23, since I work on firearms, but he sat down in my chair at my loading station and started to change out parts. This is the first time I have seen him do anything other than computers, he did well. I am so proud of him and I have about 1500 rounds of 9 mm to show him how to reload. Proud Dad.
