Hello folks...

I'm new here, so please forgive the "repost" if I'm making one. As one can see by my signature, I've recently become a fan of sight systems that provide a defensive advantage, should I need one. (My ego is well in check by now.)

Anyway, I've recently installed Crimson Trace rigs on both my 686 and my G19. I've got a set waiting to jump on to my 642 in LG-305 flavor. It should be a simple operation, but apparently I've not got the right tool for the job. The screw which holds the factory grips aboard is of a variant I can't figure out. At first, I thought it a standard Allen type screw, but it's not. Then I thought it Torx type, but it's not. The CTs were supplied with a flat head replacement screw, so whatever it is, I need it for about 15 seconds.

Surely someone knows what I can go and pick up locally, to extract this pesky screw?

Thanks!

Insane quetion, I know...Can you see the screw head? There is a set of grips that "snap" on and require a little V shaped tool to remove, or, a couple credit cards...If thats the case, check back and we;ll tell you how to get them off.
 
Yes. The screw head is exposed. It looks like an Hex type Allen, but it's not. The base of the indent isn't flat, but rather concave, I think. I have the V shaped tool that came along with my 686, and it's not that, either.

I'll snap a photo later, if nobody has any ideas.

Thanks!
 
Here's a meaningful photo:

Apologies for the microdustbunnies. This rides around in an ankle rig a lot. I suppose I need less fuzzy socks.

Thanks in advance!

I have not seen this one before?

Can you show a photo of the other side of the 642 grip?

Check out smith-wesson.com.

Click on "search by model#...642

Click on items shown...then click on "enlarge photo" of each item.

Photos either show a slotted screw or no screw at all???
 
460v LAC: Interesting. My 642's grip doesn't match any of those shown in the online catalog. The shows a DOM in February this year, and I purchased it recently, NIB from a well known retailer. The opposite grip is identical save the fact that no screw is visible.

I'm on the phone with SW customer service now. I'll report back.

Thanks guys,

For future reference, it's a Torx T10. (Some folks call this a "star" bit.) I called Smith and Sesson per Dave's suggestion, and this is what I was told.

I had tried a T10 from my tool box with no luck. Little did I realize that the cheap tool I was using had been previously rounded off. I dug up another from my drill bits kit, stuck it in a hand driver, and the grip was off in ten seconds.

Now we know. Thanks guys. Now I can sight this beauty in.
 
The new fishscale three finger grip I got from S&W uses a standard Allen wrench. Why in the world S&W is using this type of screw is beyond me!

p.s. This new grip is noticeably smaller and thinner than the Uncle Mike's three finger combat grip.
