Joining in on this thread because I'm a little confused with regard to the use of a laser on a Shockwave. If it's simply for training or "fun" target shooting that's one thing but let's think for a minute about a couple of scenarios where a Shockwave might be used in threat situations.
First is facility defense or facility cllearing. The size of a Shockwave lends itself to clearing a facility. Is it better than a pistol, maybe yes or maybe no. Is it better than a shoulder fired shotgun with an 18.5 inch barrel, maybe yes or maybe no. However, in clearing a facility (one of the last things you really ever want to do) you must maintain positive recognition of your surroundings at all times. Judicially using a flashlight, using a momentary off and on technique, allows positive identification of either a friendly or a foe. From both a legal and moral point of view you better have positive recognition of a threat before firing. I do not know how you can accomplish this positive recognition with a laser.
For me, the Shockwave is best suited as a work or field gun to be used against outdoor threats like bears, mountain lions or coyotes as examples. It's an excellent companion for fishing, for hiking, or for working everyday in areas containing potential wildlife threats. However, in an encounter with a bear or mountain lion you will likely have only 2 to 5 seconds to respond. You might be lucky to get off two shots against a full charging of a bear. A mountain lion, who can leap up to 20 feet, maybe even less time to respond. Certain avoidance is your best weapon but if threatened you best respond quickly. In these situations, I'd think the ability to use a laser would be suspect and frankly a detractor.
From my personal experience, unless a person lacks upper body strength or is very recoil sensitive, you can aim a Shockwave even using 3 inch Brenneke slugs (bear defense). Shooting "from the hip" is a proven technique using either a pistol or shotgun however it takes much practice to develop the technique. Many folks tend to shoot high when learning this technique. Repetitive shooting is require to master this technique. I'd personally rather invest in ammo vice lasers if that's your goal.
These thoughts are certainly not given to offend anyone or to downplay the use of a laser. They have their place, especially with a pistol, used in conjunction with a flashlight. I'd just like to better understand it's intended use coupled with a Shockwave. Regards.
