Hey everybody, I just purchased my "first" Glock from a friend: a G21. I did own a G23 about 12 years ago but I wasn't very accurate with it and traded it quickly. But, I love this new .45. I have been a 1911 guy for years but after shooting the G21 (3rd gen) I was sold on it. So far the only mod I have made is the 3.5lb connector and a surefire 300. I'm using a Safariland drop-leg holster. I plan to put on a threaded barrel as soon as my paperwork goes through. Any advice/suggestions from G21 owners would be appreciated, especially concerning suppressors. My sights are stock nightsights and I do not plan to change them for the suppressor. I have heard that you can just "see-through" with both eyes. This is typical of my aiming style anyway, so I look forward to seeing how this works out. Thanks in advance for your comments.
