For the Citadel 1911 .22, replacement firing pins and springs are best sourced directly from RIA/Armscor (manufacturer of Citadel) or dedicated 1911-22 parts specialists like ZR Tactical Solutions or FiringPins.com. The .22LR version uses specialized, often thinner, pins compared to standard .45 ACP or 9mm 1911s, meaning standard 1911 firing pins likely will not fit.
Where to Find Parts:
ZR Tactical Solutions: Offers durable upgraded, Wire EDM cut steel firing pins specifically for GSG/Sig/Citadel 1911-22 models.
FiringPins.com: Stocks a wide selection of, USA-made precision firing pins, including models often compatible with various 1911 clones.
Armscor/Rock Island Armory: As the maker of Citadel, they are the primary source for factory replacements.
eBay: Sometimes lists specific "1911 .22 TCM/9mm" firing pins that may match, though dedicated .22LR parts are preferred.
Compatibility Notes:
1911-22 vs. Centerfire: The Citadel 1911 .22 is a dedicated rimfire pistol. The firing pin is generally not interchangeable with standard 1911 firing pins (e.g., Wilson Combat, Ed Brown) designed for 9mm/.45 ACP.
Springs: While the firing pin is proprietary, standard 1911 firing pin springs may sometimes be adapted, but it is highly recommended to buy the specific spring to ensure reliable ignition.
