Thinking about adding one of the Surefire DG switches to my pistol. I like the idea of not having to change my grip to activate the light. I did a search here and came up with next to nothing regarding the DG switch.
Does anyone here use these?
What do you think, are they durable or flimsy?
How do they attach, just to the back of the X300?
Will the light activate when holstered?
Any other comments welcome
You might try a search for posts by one of the moderators here. John_Wayne777 wrote up a an evaluation on his experiences with a Surefire DG switch. I believe that was on the Glock platform, and not the Beretta. YMMV.
But I have found his posts very instructive on the use of lights and lasers, and have incorporated it into my training sessions.
I am personally a fan of the x300 as well.
Just did a search on all the threads he has started and came up with nothing. 
If you can find it I’d sure appreciate it.
Big fan of the X-series, and the DG switch. Mine goes in and out of duty and CCW holsters daily, with no issue in terms of light discharges. I’ve had it for a couple years, and its starting to show wear on the underside on the protective coating. Still works fine, though. If it stops working, I have a lot of faith in Surefire’s warranty and CS; they’ve been good to me.
Depending on your holster, if it puts a lot of pressure on the grip just below the trigger guard, you might have a concern about light discharges. However, I know of no holster that does this. The biggest issue is fit; most weaponlight holsters don’t take a pressure switch into account, so some time with a heat gun or a file might be in order.

The DG switch is durable and I would not consider them flimsy.
How do they attach, just to the back of the X300?
Yes they attach to the back of the light by replacing the battery box cover.
Will the light activate when holstered?
I have never experienced this unless I intentionally activated it.
Any other comments welcome
The nice thing about the switch is that it allows you to activate the light regardless of what type of grip you are using.
Unless they somehow improved the current DG switch I wouldn’t use anything else.
Thank you
Thanks again.
I also had no problems with the switch installed in mine but after a while I took it off because was so accustomed to light operation without the DG.
I use them on all of my X200-300’s that I use on my Glock pistols.
I have been using a DG switch with my X300s and Glocks on duty for over a year. I love being able to activate the light just by squeezing my middle finger. It works the same using one hand or two. A couple of observations-
I use double sided duck tape to keep the switch tight against the triggerguard.
I also reinforce the bottom of the switch (part that is under the triggerguard) by coating it with multiple layers of superglue. You can build up quite a thick protective layer by letting each thin layer dry, then adding a new layer. Doing this protects the rubber from the constant rubbing on my Safariland 6365.
Bottom line is- I wouldn’t use an X300 on my duty rig without a DG switch. It’s well worth the money.
It seems that almost everybody likes these switches.
I like to have a pretty high grip on the gun. My question is, does that little bit of extra material below the trigger guard seem to make the pistol ride higher in your hand?
You can also patch a wear point in the coating as well as reinforce it by using a bit of high quality electrical shrink wrap. Almost looks OEM and makes it much stronger. Various holsters can cause wear on the switch, but you can usually take a heat gun to them to fix the issue.

I use a DG-11 on a Glock 34 and X400 in a Raven Phantom worn as an IWB. Have had no issues with lack of durability. The DG is a nice tight fit up under the triggerguard. Doesn’t interfere with the Raven holster at all.
I like this setup alot, as it allows me to activate the light and laser just by taking a normal firing grip. So I don’t have to remember to reach forward and flip a lever in a high stress situation.
I use this for concealed carry and home defense.
The X300, X200a and X200b also work well in this setup.
Can’t comment on the Beretta/DG-xx setup as I have no experience with that particular DG switch.
Thanks again for the replies guys. Ordered my DG-20 from Brightflashlights.com today for $68.00. They sure do have good prices on Surefire products.
I had to do this to mine when I first got it. My 6004 began wearing on it before I modded the holster, worked pretty slick and looks “factory”.
Got my DG switch today. I like it.
I’m considering going with one of the SF DG switches, but I’m curious if anyone is rocking one on an HK45? Will the switch from the USP work well with the HK45?
Fantastic suggestion!
I’ll be interested in seeing an answer to this as well. Bright flashlights was supposed to get back to me a couple months ago with an answer and hasn’t.
