The caliber is the main draw. Owners who chose the G20SF specifically want 10mm power, and most come away satisfied with how it performs. Reliability is consistent, fitting the Glock reputation. The SF frame is frequently praised by shooters with medium or smaller hands who couldn't get a comfortable grip on the standard G20. Recoil is the primary topic in negative discussions. 10mm is a stout round and the G20SF is no exception; some users find it manageable while others consider it the limiting factor in rapid fire. The weight at 1.9 lbs full is worth noting for anyone who plans to carry it all day. A segment of owners discusses the 10mm's versatility, from hunting to bear defense to range work, as its defining advantage over other platforms. Aftermarket support is solid due to the G20 platform's longevity. Price-to-performance discussions are generally favorable given the cost of other full-size 10mm pistols. ## Pricing **2 offers available** | Vendor | Price | |--------|-------| | Gunbuyer Com | $546.00 | | Guns Com | $929.99 | ## Similar Products - [Glock 20 Gen 4: Versatile 10mm Striker Pistol, 15-Round Capacity](https://gunsnation.com/p/glock-20-gen-4-versatile-10mm-striker-pistol-15-round-capacity/UCDSUO2eQ) - [Glock 29 Gen4 Subcompact 10mm Pistol - Ultimate Concealed Carry Power](https://gunsnation.com/p/glock-29-gen4-subcompact-10mm-pistol-ultimate-concealed-carry-power/UCDSUNpdi) - [Glock 20SF Full-Size 10mm Powerhouse - Reliable Semi-Auto Pistol](https://gunsnation.com/p/glock-20sf-full-size-10mm-powerhouse-reliable-semi-auto-pistol/UCDSUNSEM) - [Glock 20 Gen4 10mm Auto Pistol: Precision Power, 15+1 Capacity, Black](https://gunsnation.com/p/glock-20-gen4-10mm-auto-pistol-precision-power-15-1-capacity-black/UCDSUKtPo) - [Glock PowerShot G20 Gen 4: 10mm Semi-Auto with Safe Action System](https://gunsnation.com/p/glock-powershot-g20-gen-4-10mm-semi-auto-with-safe-action-system/UCDSUKgDH) - [Glock G29SF Gen 3: 10mm Subcompact Powerhouse - Reliable Concealed Carry](https://gunsnation.com/p/glock-g29sf-gen-3-10mm-subcompact-powerhouse-reliable-concealed-carry/UCDSUNUpP) --- *Data from [GunsNation](https://gunsnation.com)*
