Are you saying that the commercial P225 was already in production?
For years, the
Polizei relied on the
P1 (Walther P38, .32 cal)
P2 (SIG P210, 9 mm)
P3 (Astra 600) service pistols, until the mid-1970s when the West German government adopted a number of new requirements:
1. feature a DA/SA action
2, 9×19 Luger chambering
3. 8 round magazine capacity
4. ability to de-cock the pistol via an external safety or de-cocking lever.
P4 - Walther quickly added the de-cocker to their P38
P5 - Walther later submitted an updated design to meet all the new requirements the Walther P5 was unpopular
P6 SIG Sauer
the SIG Sauer P220 was developed for release in 1975 for the Swiss Army as a replacement for the SIG P210, which had been developed during World War II;
Initially, the P220 was submitted; The original 1975 SIG Sauer P220 had a 'heel-mounted' magazine release located at the rear of the magazine well and a lanyard loop
the older model 220 slides were stamped from heavy gauge steel whereas the current production models are milled on a CNC machine. The slide of stamped models were folded into a "U" and have an end piece at the muzzle end which is welded in place, to complete the slide.
The stamped slides feature a removable breech block. This breech block is pinned to the slide with two concentric hollow roll pins, one pressed inside the other, with their split ends opposed.
Instead of the locking lugs and recesses milled into the barrel and slide of Browning-derived weapons such as the Colt M1911A1, Browning Hi-Power and CZ 75.
The P220 variants (and many other modern pistols) lock the barrel and slide together using an enlarged breech section on the barrel locking into the ejection port, designated the "SigSauer System".
The SIG P225 (introduced in 1978) is a more compact version of the SIG P220.
The P6 (1978 to 2000) was a slightly modified version of the P225 to conform with new requirements.
SIG P6 vs. P225 Differences
Four main differences between SIG’s standard P225 and the
Polizei-designated P6:
- mainspring weight (12 lb.) increased, therefore heavier trigger pull
- external markings, P6 roll mark on the slide
- feed ramp geometry, to improve reliable feeding of hollow point ammunition
- notched hammer spur, would deform if pistol dropped on its hammer, alerting armorer inspection; era of poor holster retention designs
An estimated 40,000-ish SIG P6s were in circulation before the
Polizei retired the SIG P6 in 2000
P7 Heckler & Koch’s new PSP (Polizei- Selbstlade-Pistole or “police self-loading pistol”)the H&K P7 was; too expensive for most
German agencies to purchase
P8 less-expensive polymer-framed H&K USP
My Sig P series chronology chart as I understand it.
The classic P series mfg. with carbon slides were folded into a "U" profile like a pizza box with the muzzle and rear end subsequently cap welded to complete the slide anatomy.
