I was pleasantly surprised...I almost never shoot slow fire. Happy I didn't get overly excited with the grouping and then choke and throw a couple!

The SS comes with a magwell which I installed and like a lot. It's a keeper but how much more gun is it really over a 17? The groups with the 45 were great (for me) and I prefer the trigger on my 19x. I was a little faster on the timer with the SS but I don't think enough to justify the price difference. At some point, I may get into red dots for pistol and this will be the one I go for and seems to have the better mounting system. IDK...your mileage will vary and this is one mediocre shooter's opinion.
