I was referring to civilian commercial sales .... aka... Local Gun Shops.

Police orders were a whole different matter.... S&W (Sig and Beretta also) was very accommodating........grips, sights, # of magazines.
decocker only, mag disconnect.... credit for old guns... whatever it took to close the deal.

Even special guns for upper management.. ....... One chief got a two tone Sig 245 with a hard chromed slide...... another Dept got Single stack Beretta 92 Compacts (Type-M) for Lt's and up. Another Sheriff's Dept got Beretta's DAO single stack guns with mag disconnects .

Some were put together by local Cop Shops..... one here in the Burgh would even send Sigs up to a place in Erie to get them nickeled or hard chromed(?)

Close the deal was the name of the game.......while friendly the 3 local Police Supply houses (I know of) were very competitive.
