Sig Sauer p220
Hi all, I have been following some p-220 sigs on the other side and I noticed that there is a "step" at the transition of slide to the frame at the rear of frame rails. Is this an indication of;1) hot loads ;2) link pin wear;3) alloy frame wear/fatigue; or what? thanks.
Sorry, this is only on used p-220's- the new one have a smooth transition.

There is nothing wrong with those Sigs, that is normal due to the rounded rear surface of the slide.
These two are mine..............

Nothing wrong with those first four.
You're looking at guns made over 20 years apart and what you're seeing isn't due to any sort of wear, instead just changes in their manufacturing process over the years.
Notice one of these pistols even has the old, original European-style heel magazine release.
However, when considering purchase and looking at both early/new specimens there are differences you should be aware of.
- The absence of a hammer reset spring. This is designed so that when the hammer is down it's automatically moved rearward to it's safety intercept notch. This prevents the hammer from resting in direct contact with the firing pin and creating danger of an AD if the hammer receives a hard blow (dropped [:0]).
Some think that seeing a SIG's hammer drop using the decocker looks unsafe, but these pistols are designed with multiple safety systems to prevent discharge when decocked properly. Lowering the hammer manually IS dangerous due to it bypassing/negating these features.
The absence or presence of this spring can easily be determined by looking at the rear of the frame where the hammer reaches full arc. A small polymer insert (appears square when viewed from the rear) indicates the gun has this safety system. Look at pic #10 of the NIB pistol you posted for an example.
- The earlier models used a 'bow' style trigger bar spring, which has been known to break on high round count guns. This issue was fixed by introduction several years ago of a 'safety pin' style, coiled spring.
You should also be aware that these two springs require grip panels of different designs.
- SIG eventually switched from a metal to a polymer hammer strut seat. This change also resulted in a hammer spring with slightly different trigger pull characteristics, but this is rarely noticed by any but the really serious SIG shooters.
The newer type also requires different design grip panels.
The upside is that it's a more simple design and makes disassembly of the pistol much easier.0 -
Thank you very much for clearing that up for me- txs thanks for the additional info.
