So, long story short, I live with my girlfriend and her 13yr old son and there have been some situations with him (e.g., him and his friends entering our room and searching through stuff when not home, making threats to other kids at school involving shooting, etc.) that make her feel uncomfortable with me having any firearms in the house. Yes, they are currently secured in a safe, but she thinks this is best. We're trying to be good role models and also are looking into counseling. She is important enough to me, so I am willing to find a compromise. I feel like I have to explain this to shut down all the internet assumptions.
What is relevant: I have a way to secure my firearms about 30 minutes away, however, will probably only have access to them when going to a range or match. I currently dry practice with my gun (g19 with 507c and LTT grip anchor) multiple times per week and am looking for a way to keep that up. Based off what advice I would give someone else my ideas are (on top of live fire when possible):
1. Blue gun. I already have one and know it can work for most handling skills (visual indexing, drawing, grip, and a pseudo "trigger press" on a "dead trigger"). I've seen some footage/pics of people having an RDS mounted on their gun. Is there a specific model as most of the time it has been orange or yellow for Glocks (not an official "blue gun")? Does anyone have any advice for mounting one?
2. Airsoft. I would get an Umarex, but have read mixed things about their triggers and what holsters they fit. I think if I can get a RDS on a blue gun I could do most work with that and would use this primarily for trigger work. I know there is some trigger differences and have seen people state 19/2011s are closer in similarities to their real-life counterparts. Is this true? I've been wanting to buy one and this could be an impetus to switch platforms.
3. A SIRT gun. I definitely don't want this due to the laser. I would purchase for it if it was more similar in terms of grip, weight, and trigger. How do they compare to airsoft when it comes to the trigger?
I know this has been asked before, but my additional questions are above based off what I've read/hypothesized for my situation. I understand none of this is ideal but I'm going to try and make it work the best that I can.
Huge thank you to everyone who replies!
