I have a SA 1911 that upon close inspection seems to have a canted hammer. In the first pic you can see wear on the hammer is just on the right hand side where it makes contact with the slide during cocking. In the second and third pics the hammer looks slightly canted to the left. Just curious as to what may be the cause. The gun has not failed to bang however.

Hammer pin hole in the frame not parallel? Have you removed the hammer and inspected it to see if it is of normal dimensions? I hear SA’s CS is very good...I’d reach out.

Didn't have time to add these into my first response until now.. sorry.....

If the weapon has been torn completely down at some time-- it is possible that a mainspring housing pin - which is the same diameter but headless- was put in the wrong spot. It is also possible that the correct hammer pin was put in place- but from the wrong direction. The safety lever will normally keep the headed side of the hammer pin from walking out towards the safety, but, it doesn't help much if the head is on the wrong side of the frame.

Has the hammer always been canted or is this a somewhat recent development?

As XTCBX mentioned above SA's customer service has been on its A game... so don't hesitate to reach out to them.

You’re probably on the right track.  There’s so many potential geometric tolerancing issues going on in a pin in a hole scenario.  Parallelism to some datum. Holes being concentric to each other. Holes having true position to generally 3 datums, perpendicularity to a datum.  I’ve been measuring stuff like this for 38 years. All of these are probably toleranced to, oh, probably .0020” or tighter. Deviations so small that they’re not easily seen if the deviation is under .0030” unless you have exceptionally good eyes.  It takes tools with 50 millionths of an inch resolution (.00005”) just a smidge (a real technical term  .  And repeatability of one thousandth (.0010”) of an inch, to measure it properly.

Yeah, I’m gonna reach out to SA today. I have not completely disassembled the gun yet since I bought it. Just field strip for cleaning. I suspect it’s always been like this and I just now really noticed it. My concern, as well as what you guys addressed, is that the sear may only be engaging one of the hammer hooks.

Well, I reached out to SA, sent them the pics and they think it looks normal. 😳 Any suggestions or anyone there I should speak to directly? I may just say fuck it and disassemble it and measure everything myself.

Is there any wear along the side or the hammer itself?

I'd call back and get a name.... make sure they understand that WHEN it starts doubling or comes apart and someone gets hurt- that the persons name who said it looked OK was gonna be front and center in the lawsuit.

Only on the face where it makes contact with the slide and only on the right side. If you mean internally, I haven’t disassembled the gun to look closer. I did finally talk to someone else at SA and I’ll be shipping it to them. I guess the pics don’t do it justice because it is canted. Funny how you guys can see it from the pics though and they couldn’t.

It is possible with SHOT going on that you might have gotten ahold of a 2nd or 3rd string support guy- or the janitor or waterboy instead of one of the Varsity CS people.

I spoke to Vickie in CS and she’s the one who told me a “tech” said it looked normal to him.

Either way, it’s going back to them to look at. But I will be asking for an inspection report on it.

Good God, Man.  Haven't you ever played billiard or pool?  When the primer is struck with a firing pin that has not been hit squarely, it will most certainly cause your shot to go to the left.

That's what causes that problem.

True story.

In all seriousness, there is no way in hell that is within spec...

My guess is it's doing that because the sear is uneven, where it contacts the hammer hooks, or somehow the hammer hooks are not even.

I'd tear it down and look for uneven wear on the hammer hooks and sear.

Be interesting to see what CS says.

Coming in late... here's my 2 cents..

As XTCBX stated, the hammer and sear pin holes have probably been mis-drilled (Have seen this).

You can always replace the hammer first to see if that is the culprit. If not, a top quality 1911 smith can re drill the holes and place oversized pins squared with the frame.

I believe Bill Laughridge of Cylinder & Slide can do this (he has worked on two of my 1911's).

UPDATE: 

Ok, so I finally got around to addressing this issue. I didn’t send the gun back to SA. I ended up buying a Tactical 2 hammer and sear set from Cylinder and Slide. What I did was put that set into my RO Elite Compact (my carry gun) and I took the stock hammer and sear from that gun put and put it into my full size RO that had the canted hammer. Everything looks straight and works as it should (did all the function tests). So its not the pin holes.

Afterward I put the full size RO’s original hammer on the flat of my vice and you can see the difference in the gaps on each side.

Needless to say I was pretty surprised.    I know SA uses MIM parts so I can only think that this maybe happened during the process of making the hammer.

The asymmetry that you see when the hammer is held against a flat surface certainly isn't impressive craftsmanship, but it's not necessarily something I would worry about. It's just clearance. I can think of a few reasons why it ended up like that, most of them being some flavor of amateur hour fuckery.

Note that I've only explained away one thing that you've described; other issues are other issues.

Actually, I think I designed one of the MIM parts on your gun. 

Hold your fire, everybody. It was NOT the hammer. 

As I said, the gun never failed to go bang, but I wanted to address it once I really looked at it in case it may have been  something such as the pin holes being misaligned like XTCBX said.  Granted at some point I’ll be upgrading the internals to tool steel parts, its nice to know its not an issue with the frame itself.
