The PSG-1 is a heavily modified G3 rifle with semi-auto only functions. Most claim it to be the most accurate semi-automatic rifle in the world, however it is quite expensive. The current price to Law Enforcement today is about $10,000 per unit. Since no more rifles are being imported for civilian sales, those original German guns that are currently in the country have risen to about $15,000 per unit for a pristine example.
An HK-91 made to withstand the import ban on firearms. Simply put, it's still a fantastic weapon, even the stars of the movies using them love it. Most of them look like PSG-1s with shorter, thinner barrels and front grips.
NOTE: Due to the relatively low number of SR9Ts and SR9TCs imported to the United States, most of the SR9 variants appearing in Hollywood movies are actually conversions of HK91s done by Hollywood's armorers. Most of them lack the forward assist, a feature that the real SR9 series shares with the PSG1. The images here on IMFDB of SR9s are images of actual movie "SR9s".
The SR9 does NOT have a forward assist, it uses the standard G3 scope mount which the forward assist would prevent. The T and TC use different furniture, not different recievers. http://www.fototime.com/EF7CB2D7F79B75C/orig.jpg --Zurak 47 11:47, 22 August 2009 (UTC)
A much more common G3 variant than its predecessor, the PSG-1. The MSG-90 is made to withstand more harsh conditions without sacrificing capability, and coincidentally is a little bit cheaper than the PSG-1.
