When I got my new shield, the rsa was not lined up perfectly and caused trouble moving the takedown lever and slide. It was straightened out before firing the first time and appears to be fine, but with reading all the threads about problems, I went ahead and called S&W for a replacement now since I know about the backorder issue. I wonder if it would be worth it to order 1 or 2 more once G&R has them back in stock? For $9, it's cheap enough. I still want to order a couple extra mags so I'd have no issue getting to $50. Is the stainless one where you have to send in the spring a better choice?
