Why would you be swapping parts between an almost identical pistol? Which parts are you talking about?
I am talking about magazine springs, magazine base plates (one extended by 3-4mm would be awesome), recoil spring, trigger spring and other parts specifically that normally get replaced over time . I have been in contact with Bond Arms's head of PR by email already in regards to this and have been told those items
*should* be interchangeable (intentional to keep Bobergs running) where a few items will not, namely the locking block, barrel and magazine body (the feed lips were modified and the locking mechanism changed slightly according to Bond Arms).
The Xr9-L was criticized for not being able to handle some 9mm that wasn’t crimped with enough forte; boberg identified some recommended ammunition that included plenty of defensive 9mm, as well as ammo to avoid completely
Also some criticisms about service interval; certain parts had to be lubricated after X amount of rounds
Other criticisms was it being double action only and no slide catch & release and no last shot hold open
The ammunition was a large factor: I reload for it and the crimps have to be solid.
I don't see the cleaning as an issue based on the design. The pistol was designed to be a back-up and/or self defense pistol, not a range target pistol: leather cures and body sweat would need to be cleaned from it often. Although not intended as a range only firearm, it is too awesome not to have, in my opinion only of course.
Again, designed as a back-up and/or self defense pistol the DAO and no separate slide lock (disconnect lever can go half way for this and auto closes if you pull the slide) is a strength, again IMO only. Lack of hold open, again, if you empty the magazine in the intended self defense situation, you have bigger problems...
... again, just my opinions.
