The Kel-Tec P15 is a striker-fired 9mm that fits 15+1 rounds into a 14-oz frame. That combination (full-size capacity in a compact, light package) is what the P15 is built around.

Features 

 
The steel slide has a black nitride finish that handles salt and moisture well. HiViz sights give good contrast in most lighting conditions and are faster to pick up than standard black sights. The stippled green polymer grip is ambidextrous, which matters for left-handed shooters who often have to work around guns designed exclusively for right-hand use. 
 
The integrated Picatinny rail accepts standard weapon lights and lasers. The grip safety adds a layer of passive retention that some shooters prefer for carry. At 14 oz unloaded, it's noticeably lighter than most 15-round 9mms, which can translate to more felt recoil on the range, worth knowing before committing.

Discussion around the Kel-Tec P15 Green 9mm centers almost entirely on the weight-to-capacity ratio. Fourteen ounces for a 15+1 gun is a real outlier in this class, and most owners bought it specifically for that reason.

Affordability is a regular talking point. Compared to other compact 9mms with similar capacity, the P15 comes in at a lower price, which makes it an appealing entry for buyers who want a high-round-count carry option without spending at the premium end.

The green color attracts notice. It's a deliberate departure from the standard palette and generally gets positive comments from people looking for something less generic.

Recoil comes up frequently as a practical consideration. The lightweight frame means the gun moves more than heavier alternatives; most owners adapt to it, but it's a real tradeoff for some. Feeding and ejection reliability is reported as generally good, though there are periodic accounts of issues in specific conditions or with certain ammunition.

Ergonomics divide opinion. The grip works well for many shooters, but some find the feel awkward during extended range use. The consensus is that trying it before buying is worth the effort if grip feel is a priority for you.
