Browning product lineup was due to its poor sales and its then-'space age' appearance (similar to the AR-15/M16). These particular P220s (or Browning BDAs) will have the stamping scroll which reads 'Browning Arms Company Morgan, Utah and Montreal PQ' on the left hand side of the slide and 'SIG-Sauer System Made in W. Germany' on the right-hand side with the serial number scrolled beneath. The Browning version has the sides of the slides polished and blued. The frame is aluminum. The handgrips have Browning on the right side only. On the right side of the slide is the serial number. The Browning BDA 45 shown in the photographs has a production series number starting with 395. The RP that follows shows that this particular handgun was manufactured in 1977. It was offered for sale in .45 ACP, 9 mm, .38 Super (a rare model) and 7.65mm Parabellum (an even rarer model). Some units were adopted by Huntington Beach Police. P220 Rail The P220 Rail (or P220R) is effectively the same as the P220, but comes with an equipment rail located on the forward end of the frame of the firearm for accepting accessories such as a weapon light or laser sight. While the provided rail is similar to the Mil-STD-1913 Picatinny rail design, as implemented by SIG for this gun it has a proprietary cross-section form that conflicts with some early design Picatinny-compatible equipment. The P220R with its rail has become the standard configuration of the majority of recent and current production P220s. P220 Carry A new P220 with a shortened barrel (3.9") and slide, but a full-sized frame. It is available in DA/SA, SA, and DAK variants. All models with the exception of the SAS concealed-carry version come with an accessory rail. P220 Compact A recent variant that comes in four versions: blued with beavertail, stainless (two-tone) with beavertail, blued with rail (no beavertail) and stainless with rail (no beavertail). It features a shortened slide, and a compact frame and has a capacity of 6+1. It is possible to use the 8-round magazines of the P220 Carry which will give it an 8+1 capacity. Adapters are available to cover the portion of the magazine which protrudes from the bottom of the grip. It is essentially a replacement for the discontinued P245, and is meant to address complaints about the P220 Carry's full-size frame in a concealed carry pistol. P220
