As long as the cap stays in place when you're shooting it, it should be fine. You need to be careful with it when removing it, putting a small flathead screwdriver under the long clip part and gently lifting up on it will get it out usually with no issues.
If you need more, they are sold in bags of 3 and I think I got them shipped to me for a total of $9 or so.
