As another lefty and the owner of a BPS for 12 years I can say that you will really learn to love that gun.

Mine is a bit picky with respect to slugs. Seems it has a taste for the "good stuff" like 3" Federals, but it shoots great groups even 100 yards and beyond. I did find that it was not so fond of 2 3/4" slugs. Regardless of what I used, the 2 3/4" slugs just did not shoot as well as the 3".

I have never regretted buying that gun, and pick it up every time over my 870 Wingmaster.
