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

Both are optic-ready 9mm carry guns within 0.1" of each other in overall length (6.5" vs 6.6"), and the gap is capacity against size. The Springfield Armory Hellcat Pro OSP 9mm holds 15 rounds to the Glock G43X MOS 9mm's 10, with a 3.7" barrel against 3.41". It is also the narrower and shorter gun, 1.0" wide and 4.8" tall against 1.1" and 5.04". The Glock is lighter by 2.45 oz (18.55 oz vs 21.0 oz) and cheaper by $88 ($582 vs $670), and its trigger is listed 0.1 lb lighter, 5.4 lb against 5.5 lb. The Hellcat Pro comes with a tritium/luminescent front and a Tactical Rack U-Dot rear; the G43X MOS has fixed sights. Both include two magazines.

Pick the Glock G43X MOS if:

• You want the lighter gun at 18.55 oz, 2.45 oz under the Hellcat Pro
• You want to spend $88 less ($582 vs $670)
• 10+1 is enough and you would rather carry the lighter pistol

Pick the Springfield Armory Hellcat Pro OSP if:

• You want 15+1 instead of 10+1
• You want the narrower, shorter gun: 1.0" wide and 4.8" tall against 1.1" and 5.04"
• You want tritium/luminescent front and U-Dot rear sights from the factory

The Hellcat Pro gives you five more rounds in a slightly smaller cross-section; the G43X MOS gives you 2.45 oz and $88 back. Both are already cut for a dot, so the optic is not part of this decision.
