Detailed Features 

 
The PM45 trades capacity for compactness — 5+1 in .45 ACP from a gun that weighs under 1.3 lbs loaded with an empty magazine. The tradeoff is deliberate: this is a deep-cover pistol where size and weight matter more than round count. 
 
TruGlo tritium night sights give you visibility in low light without battery dependency. The matte blackened stainless slide resists corrosion while keeping the profile subdued. 
 
The DAO trigger eliminates the need to manually cock the hammer, which simplifies the draw sequence and removes one manual safety consideration. Kahr's DAO is generally regarded as one of the better DAO triggers in the market — smooth and consistent with a moderate weight. 
 
The textured polymer grip provides adequate traction given the compact dimensions. Overall length is 5.67 inches, height is 4.5 inches — small enough to pocket carry with the right holster. 
 

Usage 

 
This is a deep-concealment .45 ACP option. The caliber choice means you're accepting 5+1 capacity for the stopping power of a larger bore — a tradeoff that makes sense for ankle carry or as a backup gun. Recoil is more pronounced than with larger-framed .45s due to the light weight. The TruGlo night sights make it viable for low-light defensive scenarios.

The Kahr PM45 draws a consistent set of reactions from owners: appreciation for its concealability and caliber, honest acknowledgment of its capacity limits and recoil.

Compact size for a .45 ACP is the defining selling point. Most owners specifically chose the PM45 because they wanted .45 ACP in a package that fits deeper concealment than a standard-size pistol allows. This is a niche the PM45 fills well.

The TruGlo night sights are well-regarded. Owners who carry for self-defense appreciate them as a practical feature rather than a cosmetic one.

Kahr's DAO trigger gets qualified praise. Most owners describe it as smooth and predictable after break-in, which typically takes 200+ rounds. Factory smoothness is not the same as a 1911 SA trigger, but for DAO it's considered among the better executions.

The 5+1 capacity comes up in nearly every discussion. Most buyers have already accepted it as the price of the compact size; a few find it too limiting for primary carry and relegate it to backup or ankle carry duty.

Recoil is genuinely noticeable at this weight with .45 ACP. Owners who shoot it regularly adapt, but it's more fatiguing at the range than a heavier .45 pistol. This isn't a criticism of the design — it's physics — but first-time buyers should know what to expect.

Build quality and reliability feedback is generally positive after break-in. Kahr's customer service has a reasonable reputation among owners of this model.
