那一旦开始练枪之后是不是为了保持手感要有规律地去练呢？大概要多久去一次呀？

自己看吧：

from Plantinga "400 things cops know"

“Most bad guys can’t shoot for spit. They’re about as accurate as the stormtroopers in Star Wars. You’re thankful for this, except when they miss their intended target and hit a bystander. I once responded to a shots-fired call where six men on a front porch were shot at half a dozen times by three other men from about eight feet away. It happened so fast, the guys on the porch didn’t even have time to duck. But no one was hit. Not even a graze wound. I was at another scene where five bullets were recovered inside a living room and fourteen shell casings were found outside, which meant the shooter had aimed at a target literally the size of a house from fifty feet away and went five for fourteen. 35.7 percent accuracy. Shaq used to do better than that at the foul line. It speaks to the fact that if you don’t know what you’re doing and you rush a shot, it’s pretty easy to miss, even up close. People who haven’t handled weapons much don’t understand that. They don’t put time in at the range and tend not to practice the fundamentals of shooting such as stance, grip, sight alignment, and trigger control. Instead, they adopt a different kind of technique, one known in police circles as Spray & Pray. If the average criminal ever decided to take formal shooting lessons, this nation’s homicide rate would quintuple.”

子弹2毛一个，那个瓶子7块钱1个，算下来7毛一下，我按不起啊。

一下7毛，一下7毛，连响声都没有。。。关键是那个东西在哪里喷，哪里就几天不能进人，院子不够大。。。

我是觉得。。。。您关于每天拿个胡椒喷雾练习的建议不是很靠谱。

我买回家之后，全家试验了一遍，就再也不想“练习”了，那东西跟灭火器有点类似，也没啥好练习的。

您的这个建议，让我觉得您实际没有用过胡椒喷雾，甚至都不知道那东西长什么样子，有哪些种类。

用过的，体验过的，应该不会给这种没意义，而且搞不好自虐的建议。

是为了熟悉武器，不然过两个月连pepper spray 放哪都忘了。

枪给人很多false confidence，我觉得真想练还不如练刀，每天象织毛衣一样扎100次，加上跑步，日久就可以用了。不用花钱买子弹，不用上靶场。
