Features 

The OD Green polymer grip has interchangeable backstraps for adjusting grip circumference. The three-dot sight system with adjustable rear supports accurate target acquisition. A decocker button on the slide drops the hammer safely without firing a round and is recessed to avoid snagging. The ambidextrous paddle magazine release operates from either side, accommodating left-handed shooters. 
 

Usage 

The DA/SA action gives a longer first-shot trigger pull from the decocked position, with a shorter pull for subsequent shots — a configuration familiar to shooters coming from duty-style pistols. The 9mm caliber manages recoil well for home defense and range use. As a final-edition model it also draws interest from collectors who want a documented production endpoint in the P99 line.

Discussion around the Walther P99AS Final Edition 9mm OD Green covers several consistent themes.

Ergonomics are the most common praise — the grip fits naturally in the hand and the controls fall where they should. The DA/SA trigger system is well-regarded; the double-action first shot and single-action follow-ups feel smooth, and the short reset gets favorable mention from accuracy-focused shooters. The OD green finish draws appreciation from owners who wanted something different from a standard black pistol, and it appears frequently in collector-focused discussions.

Reliability across different ammunition is widely reported as solid, with few malfunctions noted by owners who have put significant round counts through it.

Criticism includes the price relative to competitors — some buyers feel similar performance is available for less, while others argue the quality of fit and finish justifies it. Holster and accessory availability draws occasional frustration, since the P99 platform is less common than Glock or SIG options in the aftermarket. Comparisons to Glock and SIG Sauer pistols appear in most extended discussions.
