Glock G43X 9mm vs Springfield Armory Hellcat Pro OSP 9mm

Both are striker-fired polymer-framed 9mms within 0.1" of the same overall length (6.5" vs 6.6"), with triggers 0.1 lb apart (5.4 lb vs 5.5 lb) and two magazines in the box. The meaningful gap is what the Springfield Armory Hellcat Pro OSP 9mm fits into that envelope: 15 rounds against the Glock G43X 9mm's 10, on a 0.29" longer barrel (3.7" vs 3.41"). It does that while staying 0.1" narrower (1.0" vs 1.1") and 0.24" shorter in height (4.8" vs 5.04"), and it ships optic-ready with a tritium/luminescent front and Tactical Rack U-Dot rear. The G43X is 2.3 oz lighter (18.7 oz vs 21.0 oz) and lists $132 under it ($538 vs $670).

Pick the Glock G43X if:

• You want the lighter carry gun at 18.7 oz, 2.3 oz under the Hellcat Pro
• The $538 MSRP against $670 is the deciding factor
• You are content with fixed irons and no optic cut, and a 6.5" overall length

Pick the Springfield Armory Hellcat Pro OSP if:

• You want five more rounds on board, 15 vs 10
• You plan to mount a red dot — it is optic-ready, the G43X is not
• You want tritium/luminescent sights and a 0.29" longer barrel (3.7" vs 3.41") in a body that is 0.1" narrower

The usual thin-vs-capacity tradeoff does not really apply here, since the Hellcat Pro is both higher-capacity and narrower. The choice comes down to the 2.3 oz and $132 the G43X saves against the optic cut, the night sights and the five extra rounds.
