I am sure it will do fine but I have noticed Buffalo Bore stuff seems hot in the standard stuff I cant imagine what their +p is like. That said I would never feed any gun I liked a steady diet of +p unless it was 38+p in a 357.
The main issue here is leading. Glock barrels have a different type of rifling than standard barrels and are more prone to lead accumulation when firing non-jacketed rounds. If enough lead builds up, that increases pressure and eventually, things could go boink.
The other issue is that the 255 grain semi-wadcutters tend to not feed well in autos. Most people using these rounds are using them in .45ACP wheel-guns like the S&W 625.
