Might want to consider switching from RST to another manufacturer with 16ga or 20ga payload in 12ga shotshell ie 7/8oz to 1oz at 1100fts to 1200fps. Such shells are available form Fiocchi, Winchester, Remington, Herter's at Cabela's,.....Soon Kent of WV with come to rescule with 3/4oz (original 20ga payload) in 2.5" case 1200fps for about $8 per box.
Just because Model 21 isn't good choice for me doesn't mean it isn't high quality well-made gun of high quality components. Hey if you switch to ole' Winchester 21 you can use them Remi Club loads and really save money on the shells! whistle A guy had one of them two trigger ones in 12ga 28" at last gun show in very good shape for $3600. Man, Perazzi charges about $20,000 for something that looks similar. crazy Talking about expensive!
When one thinks a bit and crunches some number that ole' Winchester kinda becomes affordable. I got a little slogan for you boys....Shoot more for less live happier buy old' Model 21! Good?
