Sig Sauer P211 GTO Sight Block - delete the compensator for USPSA limited optics
Welcome back to Jim's Armory. In this one, Jim installs the long-awaited sight block for the Sig Sauer P211 GTO, a part that deletes the factory compensator and makes the pistol legal for USPSA's Limited Optics division. There's a catch worth noting right away: this part isn't made by Sig at all. Here's how the install went, what's inside the package, and Jim's thoughts on the part itself.
Unboxing — Not a Sig Part, But a Familiar Name Jim opens the package to find the sight block made by Fez Works, complete with their logo stamped on the front. The kit includes the comp-deleting block itself, an extra nut (this one see-through, which Jim finds interesting), and a couple of stickers. Jim notes that Fez Works is mostly known in the space for ported barrels and matching slides, so this is a bit of a departure for them. He ordered two full sets, including extra springs and nuts, anticipating he might lose a small part during the swap.
Safety First Before touching any tools, Jim shows the gun clear — no magazine, nothing in the chamber — and double-checks before starting the teardown.
Disassembly — Guide Rod, Recoil Spring, and the Plastic Wedge Jim starts by removing the guide rod and recoil spring, then the reverse plug, disengaging the barrel locking lugs. He points out that the wedge/plug component here is plastic on the current version, and he's seen a few reports of these failing. Fez Works is reportedly working on a stainless steel version, and Jim recommends getting on their list if you want to wait for that upgrade.
With a 5/64" hex key, Jim carefully backs out the screw holding everything under spring tension, keeping steady pressure so the spring and nut don't launch across the bench.
Pro-Tip: Every 3 to 500 rounds, pull this wedge/plug assembly and clean the carbon off the front. Fez Works has pointed out in their own materials that carbon buildup here can start to seize things up, so a little preventative maintenance goes a long way.
Cleaning and Reassembly Jim uses Hoppe's No. 9 to soak and clean the carbon off the front of the component, wiping down the sides as well before applying a light coat of oil. On reassembly, he's careful to orient the part correctly rather than 180 degrees off (an easy mistake to make), then seats the wedge into its hole, applying gentle pressure with a punch and wiggling it until it's fully seated.
The screw gets torqued back to spec at 15 inch-pounds — Jim explains this as roughly the equivalent of a one-inch-long ratchet with one pound of pressure applied, times fifteen. From there, it's barrel link down, slide back on, and the plug pushed carefully back into place using a syringe-like motion to seat it properly.
The Finished Product With the sight block installed, the comp and port are fully deleted. Jim notes the front of the block is hollowed out for reasons he's not entirely sure of, but says it looks sharp regardless.
Performance Expectations Jim didn't take the gun to the range for this one, and he's upfront about why: the outcome is predictable. Removing the comp means the gun will shoot exactly like it did before, just with noticeably more muzzle rise. In his experience, these 3D-printed comps are genuinely effective at taming recoil, so pulling one off is going to be felt immediately, not something worth demonstrating on video.
He does flag one open question for owners — the size of the magwell with this configuration for USPSA use — but since Jim isn't a USPSA shooter himself, he's leaving that one to the comments section.
Final Thoughts The Fez Works sight block gets the P211 GTO compliant for Limited Optics without a lot of drama, though Jim would like to see the plastic wedge component replaced with the stainless version once it's available. If you're planning to compete and need the comp gone, this looks like a solid stopgap — just budget for the muzzle rise you're trading away.
