If you own a SECOND GENERATION P-3AT, I am in need of a couple of measurements. A caliper will be necessary.

There is a fair amount of tolerance in the positioning of the semicircular hole behind the sight and I'm trying to determine how much it varies from pistol to pistol. I have several samples already, but the more measurements I get, the better.

See the picture below. Segments A-B and K-L will indicate centering; B-C is the depth of the sight notch, D-F shows height, and F-I the front-rear length. To get D-F, you may have to measure from the top of the sight (at center of the black dashed line) straight down to F, then subtract the value of B-C (depth of the sight notch.)

Any help you can give will be most appreciated. Be sure to tell me which model pistol you have along with the measurements. Please send it to me via PM or email, instead of posting it in this thread.

Thank you very much!

Taken caliper measurements will be extremely subjective. here are mine.


AB=0.100"
BC=0.039"
DF=0.065"
FI~0.110"
KL=0.085"
BK=0.121"

AB=0.095
BC=0.023
DF=0.095
FI~0.130
KL=0.095
BK=0.120"

Thank you VERY much.

Keep 'em coming!

I can tell you that my a-b and k-l measurements are noticeably different, its annoying but I mostly use my crimson trace anyways. I've looked at a couple others and you can usually see that the sight notch is cut off center. I don't know how much difference this makes in such a little gun but it could be improved.

Here's the best I could do for my 2nd gen P3AT purchased new Aug 2006.

A-B   .097
B-C   .032
D-F   .073
F-I    .116
K-L   .111
B-K   .113

Mine is cut dead center. So are the others I've looked as well. Maybe all of them I've looked at are special for some reason but I've never seen one with a notch cut off center.

AB=.069
BC=.027
DF=.069
FI=.103
KL=.097
BK=.112

Seems to be a lot of inconsistencies here... hmmmmmm, ah ha!!

 

[gbundersea]

From all I have seen and heard, the inconsistencies are not with the sight, but with the semicircular hole behind the sight. So, while it may make the sight appear a little off, alignment and functionality are not affected.

In newer pistols, even these purely cosmetic differences have been eliminated.

Keep in mind that measuring these tiny dimensions is not easy, so variation will occur. I myself usually get slightly different results on the exact same dimension every time I measure it.

The position of the semicircular hole does impact my project somewhat though, so your input is extremely helpful!

Thanks to everyone, and please keep them coming!

Bump! Need more input!

A-B .085
B-C .030
D-F .075
F-I .110
K-L .110
B-K .125

Mine is off center. I never even noticed before. It hits where its supposed to though.

I just noticed that as well, front and rear are both right to center (anyone else see any irony in that )
