Our Assessment: Colt’s Patent Firearms Mfg. Co. is well known as the original and most recognized maker of 1911-type pistols. Ever since the design’s military acceptance in March of 1911, and the beginning of production in January of 1912 Colt has never ceased manufacturing pistols based off the original 1911 design, known in commercial trim as simply the Government Model. However, in its 100-plus years of production the design has seen many slight evolutionary changes in the name of improved (or cheaper) manufacture, product safety, and market trends. From 1911 until 1970 there were virtually no significant changes to the basic design, but the year 1971 saw the first mechanical “improvement” to the 1911-type pistol. Colt redesigned the barrel bushing from a solid cylindrical type to a spring-steel, “finger collet” bushing that gripped the end of the barrel, which had also been slightly redesigned with a slight belled end to accommodate the collet bushing. The new “Accurizor” barrel and bushing was intended to improve the intrinsic accuracy of the new Colt Government Model pistols, which were then designated the MK IV/Series 70 to differentiate them from all prior variations of the Government Model. While not as capable of superb accuracy as a true hand-fit barrel and match bushing, the new setup nonetheless allowed the typical mass-produced Colt shoot better than the older military-spec pistols with their loosely fit solid bushings and straight barrels. The new setup was successful enough that the full-sized Gold Cup National Match pistols also incorporated the finger collet bushings, although the shorter Commander models retained the use of their shorter solid bushings.

This is a beautiful Series 70 with about 97% of its blue finish remaining. Sporting a strong bore and crisp mechanics. Included is a factory magazine, box and owner’s manual. If you are a Colt collector, chances are you have a Series 70 in the safe already, but in this condition, one would be more than happy to add this one and maybe take the other one out shooting! Please see our pictures and good luck.
