  1. So far so good, continued Review by New Englander

    Time to get a holster for this combination. Alien gear has a hybrid iwb that is compatible $30, Jm custom kydex iwb $75 and Foxx trap iwb kydex $49. I'm going with Foxx, it wil be my second purchase from them. (Posted on 11/20/15)

  2. Only option I've found to fit 29sf Review by 10mm

    It fits the 29SF, though seems a little awkwardly. I need to fire it and make sure it will hold up to the recoil of full power 10mm loads. Hard to find a holster for this combination as well. That's the worst part of the defender and trigger guard versions is holsters...I have over 10 CTC lasers and all the previous have been great. Wish they made more options for the 29SF (Posted on 11/14/15)

  3. So far so good Review by New Englander

    Mounted on glock 19 gen 4, zeroed with bore laser at 10 yds. When I go to the range I fire about 100 rounds, usually fire 1 mag with the laser just to be certain I'm hitting where I'm aiming. My skill level is where I need it to be, I'm strictly an sd shooter, this laser suits my needs. So far so good. (Posted on 10/14/15)

  4. not durable Review by vicburn454

    Went dark after 140 rounds, first time at the range. Tried new batteries, to no avail. Will contact Crimson Trace and see if they will stand behind their product. (Posted on 8/26/15)

  5. Won't fit my Glock 21 Review by David

    The trigger guard is too wide for the unit to fit around. There is no way to tighten the screws. Just going to throw it away. (Posted on 6/25/15)

  6. Nice and compact Review by Tony0914

    Excellent product. Fit well and stays in place. Needed a little tweaking from factory zero but that's expected with any product. Seems durable after 800+ rounds still functions like new on glock 19. Appears to hold zero well, after almost 1000 rounds have NOT had to re zero. I don't run it on all the time I just turn it on every 100 rounds or so to check POI matching POA. So far so good, another winner by Crimson Trace. (Posted on 1/5/15)

  7. Compact and cost effective Review by CC

    I've only put about 50 rounds but not problems and I really like the platform.Great price point and I would like to see the same setup for M&P pistols. (Posted on 10/13/14)

  8. Not very durable - cannot recommend Review by Kurt

    After putting several hundred rounds through my Glock 23 my 2nd DS laser has now gone dark and no longer works. This is 2nd laser that has done this to me, the first laser did the exact same thing and was replaced by Crimson Trace. Now the replacement has broken in the exact same manner It seems these lasers cannot take the recoil or sheer number of rounds before they fail and are unusable. My 2nd laser failed after 500 rounds, tried new batteries but no avail.

    Too bad too as I really liked this sight, it just isn't durable enough as evidenced by now 2 separate DS units complete failing from just shooting with it.

  9. Great product for the money Review by Fonzi

    I installed the DS-121 on my Glock 35, (took less than five minutes). Went to the range and "zeroed" it in for 50 feet (factory alignment was a bit off). I hit the "head" shot ten out of ten times under rapid fire. (Posted on 4/25/13)
