I have about 500 rounds through my SR-45, so I would not call this a deep review; just some observations.
- Groups 45LC very slightly better than 45 ACP. Not enough difference to make a difference.
- Groups are not great; I was hoping for better. At 50 yards, shooting off bags, with a dot, I was getting 7-10" groups with 45 ACP. At 100 yards...nope. Only hitting the target 1/2 the time.
- Handles all ammo well; had one light primer strike when I was having trouble with cylinder turning in DA (see below)
- Forget birdshot. The spread is wild. i suspect the rifling is upsetting the load. No problem with 000 Buck. Fed Personal Defence gave me an average 8" spread at 15 yards.
- Faults. 1. Mine has been good overall except... after 50 rounds, there's enough dirt build up behind the cylinder that the cylinder sometimes drags. The DA is a heavy trigger pull and with the cartridge bases rubbing on the rear wall, it can be difficult to get the whole shebang moving. Keep the gun clean and lubed; it's good, but this "feature" reappears rapidly (on mine at least).
-2. The moonclips are not the best. Fiddly to load, don't grip all rounds evenly. Seems they are already on version 2 of this part.
Likes. Overall build quality is OK. Not great, but walnut is nice and it functions well enough. The blast shields do an adequate job. It's fun and a lot cheaper to run than a 410.
-Dislikes. The trigger reach is a little long for my delicate little hands.
-Overall. I like it. I had hoped for an all rounder bush gun, but I feel the accuracy is not really there for that. As a range toy; it's great.
