Springfield Hellcat Pro OSP vs Glock 48

The biggest cited difference is capacity: Springfield lists a 15-round and a 17-round magazine with the Hellcat Pro OSP, while Glock lists a standard capacity of 10 for the G48. The Hellcat Pro is also sold optics-ready (a milled slide fitting the Springfield Micro footprint); the G48 page we used is not an optic-ready model. The G48 has the longer barrel and length on paper (4.17 inch and 7.28 inch against 3.7″ and 6.6″). Figures are copied from each maker’s own page, checked November 5, 2026.

At a glance

Like for like: Springfield’s width is “Grip Width” while Glock’s is the overall width of the pistol, so they are not the same measurement. Springfield’s weights are “w/ Flush Mag” and “w/ Extended Mag” and do not say whether the magazine is loaded or empty; Glock’s are “without magazine” and “with empty magazine”, so we do not line the two up. Glock’s height is “incl. Mag.”; Springfield gives a height for each magazine. Glock notes its technical data “are rounded and do not reflect tolerances.” The G48 page we read is Glock’s non-MOS commercial G48. Springfield prints an MSRP on its page; we list none.

Which to pick (on paper)

• If capacity is the deciding number: the Hellcat Pro OSP ships with a 15-round and a 17-round magazine; Glock lists a standard capacity of 10 for the G48.
• If you want an optics-ready slide as sold: the Hellcat Pro OSP. Springfield names the Springfield Micro footprint. The G48 page we read is not an optic-ready model; Glock lists a separate G48 MOS.
• If barrel length or overall length matter: the G48 lists 4.17 inch and 7.28 inch against 3.7″ and 6.6″ for the Hellcat Pro.
• If you want the lighter printed weight: the G48 at 18.48 oz without a magazine against Springfield’s 21 oz w/ flush mag. The labels differ, so they are not a clean pair.
• If width is the deciding number: Springfield lists a 1″ grip width and Glock lists 1.10 inch overall width. They are different measurements.

We have not range-tested these; facts above are from the makers.
