I agree, once you get the hang of the Glock pistol they are extremely accurate.
I purchased a Glock when they first came out. I was always into 1911's and Smith revolvers . I had trouble shooting the Glock so I blamed the gun and sold it. Now about 3 years ago I went to North Carolina, I went to a shooting range and I rented a Glock 21. I took a few shoots and the same thing, I sucked. Luckily next to me was a sheriff shooting his Glock he came over and introduced himself and politely told me it wasn't the gun it was me. He said he carried the 21 one for many years on the job.He adjusted my grip , gave me a few pointers and just like that I was constantly hitting the X. He smiled and told me to have a great day. I still have my 1911 and revolvers but I now have 5 Glocks. I have the ameriglo sights on 4 of them. Great guns. They work for me.
