[GOTURBACK]

Hi all I wanted to know what size roll pin punch everyone is using to install the extended mag release I don't want to bugger it all up? Are there any tricks to installing it ( like the TRS ). Also if anyone has any suggestions on where to get the proper size punch that would be greatly appreciated as well.
Thanks Chris

I used a 2.5 mm hex screwdriver. Worked like a million bucks. A very good upgrade to this pistol, as you've already surmised.

3/32 will do. Don't push the pin out all the way. Push it enough that you can remove the mag release. When inserting the new release, use the top of a knife to compress the mag release spring, then push the spring + release back into the catch. Then drive the pin back. Should take you no more than 5 mins.

I got a set of Grace USA steel roll-pin punches (6 of them) for $27.49 from MidwayUSA.

If you have a drill bit or screwdriver set, you could find the size with those.

 

[TooSixy]

3/32 is what you need. Same size on all guns.

A Glock punch works wonders too, if you have one handy.

I uses a micro torx driver (not sure the size). Worked great for me!

Lowes has a full set of Bosch punches for $11. Get the set and pick the one that fits in the hole.:wink:

The more I got into firearms, I slowly bought tools to work on them. The right tool will always make it easier and less chance of buggering up the gun. I've had to start buying a second set since my son got into firearms. He keeps borrowing them and doesn't bring them back.:41:

I just replaced the mag release in my P2000 with the extended mag release. I was about to use a knife to guide the spring back into the frame but I was afraid I would scratch something up due to clumsiness. I ended up using a soft plastic guitar pick. Worked like a charm.

Great upgrade to the pistol. You'll notice a difference.

i was able to use a small allen wrench to change the mag realease and it worked great

I got a AR punch pin set with four sizes. medium small one works. the only tricky part and its easy is getting the spring set. I used a small flat screwdriver

 

[Armiger]

This was very helpful. I would add just a couple of thoughts - the spring is under pressure so be careful when you pull out the factory mag release. Its not an eye poker but could lead to " where did that little black spring disappear to". When compressing the spring with a small flat blade screw driver the spring kept getting stuck in the notch where the lip of the mag release rests. I found that coming in from the side with the blade compressing the spring was beneficial. As noted above, the only challenging part is compressing the spring while finessing the extended mag release into place.

When you compress the spring to reassemble, use a butter knife.

When you compress the spring to reassemble, use a butter knife.

Yea once you do it a bunch of times it takes a minute at most. I just use my pocket knife.

And almost every part in a gun is under spring tension. Whenever you drive a pin out, expect there to be spring tension there.
