Recently started this project, beings I was in the market for a decent .22LR pistol. Bought this Ruger 22/45 w/ threaded barrel, and decided I wanted to make it a modern-day "Hush Puppy". I couldn't bring myself to spend $450 on a Trijicon RMR, so I got the most rugged thing I could find at a lower price-range. Ended up with a Burris FastFire 3 w/ 8 MOA dot. "Why an 8 MOA dot?" you ask? Well, I ordered the 3 MOA, but ended up with the 8 MOA, and I have to say, I like it for two reasons- 1. My RMR'ed Glocks have a 9 MOA dot. This allows me to practice with a dot that's very close to the same size as my 9 MOA RMRs......truth be told, I cannot tell the difference between the 8 MOA of the FastFire 3, and the 9 MOA of the Dual-Illuminated RMR's on my Glock 19 and Glock 21 Gen 4. 2. I'm not trying to be a pistol sniper with this thing. I'd rather have faster acquisition of the dot. The 8 MOA dot only covers 2" at 25 yards (75 feet). With that said, I purchased a Huntertown Arms Guardian .22LR suppressor to go on it. My dealer lets me shoot with it every time I go, and I must say, I love how quiet it is! Once I get my suppressor approved, the project will be complete........I can't wait!
