<h2 id="history">History</h2> <p>The <a href="/facts/Sub-caliber/rzhpBral">sub-caliber</a> Colt Ace was derived from the powerful <a href="/facts/.45_ACP/hEdjsBlQ">.45 ACP</a> chambered <a href="/facts/Colt_1911/Wzb4l1cz">Colt 1911</a> to allow military, police, or civilian shooters to train with the Ace without the recoil and expense of the 1911, but with similar ergonomics and sighting. Chambered for the far less powerful <a href="/facts/.22_LR/lYgYNrNV">.22 LR</a> cartridge, its barrel was constructed (on all but the earliest models) with a hinged <a href="/facts/Floating_chamber_(firearms)/CnKcFREy">floating rear chamber</a> that amplifies the recoil when cycling the heavy slide,<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> giving it more of the feel of the larger, heavier weapon. </p> <h2 id="users">Users</h2> <ul><li> <a href="/facts/United_States/P0sCdLe5">United States</a> <ul><li><a href="/facts/United_States_Navy/xYK0fUou">United States Navy</a>: Used as a training pistol, designated the <i>Pistol, Caliber .22, Colt, Service Ace</i> (1950)<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> and <i>Pistol, Caliber .22 Colt, Ace</i> (1960).<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a></li></ul></li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="http://www.thedailytop.com/look-floating-chamber-recoil-booster-colt-ace-fascinating">http://www.thedailytop.com/look-floating-chamber-recoil-booster-colt-ace-fascinating</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Sapp, Rick (2007).
